As someone who was there for the first one on my college campus, for Earth Day I figured what could be better than wearing one of my cycling caps to work, right? Nothing greener than cycling. I went back about a decade for my hat choice, and found my old Trek mountain bike racing team hat, which was sponsored then by....of course, VW. I thought the irony was great.
